A routine service starts with fluids and filters — oil, coolant, air filter, and anything else due on interval — because clean fluid and a clear filter are the cheapest insurance a dirt bike has. From there it moves into an inspection: chain and sprockets, brake pads and fluid, bearings, cables and controls, and the cooling system.
The inspection is where the real value is. Wear items get flagged, not just replaced on a schedule — a chain with life left in it stays on the bike, and one that is stretched past spec gets caught before it costs a sprocket set or worse. Anything the inspection turns up is discussed before it becomes work on the bill. For internal engine attention beyond the routine, that is engine and motor work, and suspension service and setup lives under suspension & chassis.
